Do you have the same issue if you follow the OP’s steps to reproduce it?
Yes, but not every time.
Provide extra information to complete the original description of the issue:
This usually happens when I do not quit immediately after a flight, but leave the game running while I work on something else, such as reading forum posts. When I return to quit, I cannot, so have to kill the app in task manager.
If relevant, provide additional screenshots/video:
